I'm wondering if anyone knows the best way to fix this. I have to push down on the mill head to make the z axis slide down to where it should be, because there's a small gap between the Mill z axis dial, and the drill press crank, where they lock in to each other.





I used the threaded holes for the plastic shield to mount the z axis drive.

Take a look a my X axis drive, I used paper to fill the gap so there's no play there.
